Poriot is a native public chain of POR mechanism created by combining the advantages of POS, which can open up multiple public chains, form a "common" chain, fully support the smart contract of solid language, and use Merkel tree to prove the cross chain interoperability with eth, BSC, heco, dot, Tron and other chain assets and data. Poriot makes the gas fee of the transaction close to 0 (each transaction only needs 0.0001u), the TPS reaches 20000 +, the service delay and security far exceed the current mainstream public chain, and creatively puts forward the por proof mechanism.
